My present 1nvent1on relates tornenns ior,

the the holder of a wire drawing machine in dilierent positions relatively to the rotating wire, drawing block, and it consists in the construction and arrangement of parts as hereinafter described and pointed out in the annexed claims.

Referring to the accompanyingdrawings 1 denotes a wire rowing table- ,or bench; on which is mounted a. rolzitzible wire drewing block 2, mechanism 3, which may be of any suitable and known form of construction for the purpose of seizing the end of the Wire to be drawn. The grip ing mechanism 3, as is usual in devices 0 this class, is attached to or carried by the upper portion of the rototuble block. The lower portion of the ro tatahle biocl" is provided with a beveled casting-off flange 4 as is common in machines of this class. Mounted upon the table 1 and in suitable relation to the rota.- table wire drawing block is zi die holder 5 in'whieh the wire reducing dies are held and clamped in position by a clamping screw 6. T he die holder 5 is pivotally connected by i horizontal pin 7 with the upper end of a stud rotatable in a vertical lac-1rin o 9 attached to the wire drawing table or bench by bolts itlyconstituting a swiveled connectic-n between the tab 1e and the (lieholder.

hen the proper reducing die has been provided with a gripping me of t a 1 i er the surfa e. f the. stable vro ks iholder, .tS 'Sl)0WI L in Fig. operation of rinsing 2% end. of the 2.211113.

the position shown in F and 4, its falling movement being checkedhy the contact of the arm 13 with the stop 17. The lifting lever 11 acts as a counterweight which is held from acting while the arm 13 is held in contact with the table 1, swing to the free end of the arm 13 passing slightly past the vertical plane of: the axis of ihe lever. As soon, however, asthe' arm 13 is relieved of the weight of the die holder, the lever 11 acts by gravity to rock the arm and remove the support of the die holder 106 which then gradually descends, causing the wire to lie wound in ital on the drawing il ji 'ffiili the holder then determines the character of the spiral coil about the block 2. As the wire is wound 11 0 around 'the rotating block 2, each successive coil is wound nearer the casting-off flange, eventually bringing the line of draft into a horizontal plane corresponding with the casting-ofl flange, against which each, sue

ceeding coil of wire is then wound, the winding of each coil pushing the preceding coils upward upon the conical surface of the -ble, a wire drawing block and a grippin'g drawing block 2.
